IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 511,225, dated April 24, 1866.

i To all whom it may concern,.-

Be it known that I, H. M. SMITH, of the city of Richmond and State of Virginia, have invented a new and useful Improvement in Machines for Raising Water from Wells or other Places and I do hereby declare that the following` is a full and exact description ofthe construction and operation of the saine, reference being had to the annexed drawings, making a part of this specification, in which- Figure I is a vertical view; Fig. II, a horizontal, and Fig. III a perspective, View ot" combined brake, pawl, and lever.

The same letters refer to the saine parts in each ligure.

A is a common well-curb, which I make by nailing` boards onto four posts, which extend up about three i'eet from platform and support two rails, B B, on which the cylinder O works in ordinary bearings.

The cylinder O, I make of hollow cast-iron with journals attached, or by inserting` an inch bar of round iron into a wood block eighteen inches long and large enough to turn live inches diameter.` The iron is turned for the journals and crank and the wood rounded oit' for the rope.

On the right-hand end of the cylinder I attach a cast-iron wheel, D, about ten inches diameter, with periphery one and onelialf inch wide. -The wheelis recessed under rim about oneand one-eighth inch deep, and ratchetteeth formed inside of the rim.

I make a brake-lever in this way: Take a three quarter-inch barA of round iron about twenty-touri nches long. Make one end in form of an i, with cross three and one-half lonO. Then bend, as in Fig. III, so that one will be vone and one-half inch wide and curved to tit over periphery of D. The other part is bent so as clasp the rim ot' D, but allowing the rim with ratchet-teeth to revolve freely between the two jaws l and 2 thus formed. Now bend the bar at E at right angles, so that the two jaws will come l on top and 2 under the rim of D. Then bend the other end back at right angles at F, which forms the arm of lever, with handle 4 extending back past the curb. No. 3, between E and F, forms, when fitted onto rail B, fulcrum of lever. Thearm 4, being longest,

will overbalance the jaws and bring the underone, 2, always in contact with the teeth on under side ot` rim D, and secure it against turning back when left to its own action.

The bucket, rope, or chain may be in any known forni of construction. f

The operation is evident. Turn the crank, a-nd the pawl, being pressed upward by weight ot1 arm 4, is constantly applied to the teeth of D to prevent the descent of the bucket at any time during the ascent, if not desired. To return the bucket into the well, raise the arni of lever by handle 4 briskly, so as at once to release the pawl and apply the brake with suitable force to control the descent of the bucket,

and with increased force stop it as it reaches the water.

I do not claim any of the devices herein presented separately; but

What I do claim, and desire to secure by Letters Patent, is-

The combination and arrangement ot' pawl and brake E F 4, brake and ratchet-wheel D, and crank G, as and for the purposesdescribed.
